034Motorsport is pleased to present our new Billet Aluminum Rear Differential Carrier Mount Insert Upgrade for the B6/B7 Audi A4/S4/RS4! The factory Audi rear differential carrier bushings have voids in the rubber damping medium, which results in excessive rear differential movement (twisting) under load. This movement allows for unwanted drivetrain slop (and sometimes clunks) that can be observed when accelerating, decelerating, and shifting.
These billet aluminum inserts are designed to fill the voids in the factory B6/B7 Audi A4/S4/RS4 rear differential carrier mounts, and limit rear differential movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin.By filling the voids in the factory mounts, these inserts eliminate the associated slop and ensures that you're experiencing smoother shifting and throttle transitions, and an improved driving experience.
Installation is very simple, can be performed in minutes, and is completely reversible.

CNC-Machined Billet Aluminum Construction with Clear Anodized Finish
